Operation Thayer

Operation Thayer was a US-ARVN-South Korean military operation during the Vietnam War which occurred between 13 September 1966 and 12 February 1967.

The US 1st Cavalry Division, along with contingents of ARVN and South Korean troops, launched an operation to clear coastal Binh Dinh Province of North Vietnamese and Viet Cong troops in the autumn of 1966. Many areas under communist influence were abandoned by the local rural populations, and the communists broke up into smaller units and fought against the overwhelming might of the anti-communist forces. The allied forces lost 296 dead, while the Americans claimed to have killed 2,669 communists. Although the operation was a victory for the anti-communists, the communists were able to once again contest control of the province after the operation's end in early 1967.
